NON-CONDUCTING JACKET.

SPECIFICATION forming part of Letters Patent No. 403,700, dated May 21,1889.

Application filed February 11, 1889. Serial No. 299,444. (No model.)

To all 107mm it may concern:

Be it known that I, JOHN RILEY, a citizen of the United States, residingat Troy, in the county of Rensselaer and State of New York, haveinvented new and useful Improvements in Non-Conducting Jackets forSteam-Pipes and other Radiating-Surfaees, of which the following is aspecification.

This invention has for its objects to provide a novel, efficient, anddesirable jacket or covering for steam-pipes and otherradiating-surfaces; to provide a non-conducting jacket wherein a seriesof parallel separated deadair channels extend longitudinally within thejacket and are formed of corrugated paper; to provide a non-conductingjacket wherein an inner set and an outer set of parallel separateddead-air channels extend longitudinally to largely increase theefficiency of the structure in preventing the radiation of heat andprevent the burning or charring of the hair that maybe used to provide anovel external envelope of textile material for binding and retaining asectional non-conducting jacket on a steam-pipe or otherradiating-surface, which can be buttoned and unbuttoned; to provide anovel external binding-envelope of textile fabric havingcontinuously-wired opposite edges for keepin the latter stretched ordistended and producing a smooth surface when the parts are buttonedtogether, and to provide the external envelope with wires at the edges,that while they stretch or distend the latter one of them subserves thefunction of securing and holding the buttons or similar fasteningdevices and the other braces the button-holes, all in such manner thatwhen the parts are buttoned or similarly fastened the two wiresdistribute the strain along the opposite edges of the textile fabric toprevent the latter tearing out and provide a close union of the partsand a smooth and symin etrical casing.

The objects of my invention 1, accomplish by the features ofconstruction and combination and arrangement of devices hereinafterdescribed, and set forth in the claims, reference being made to theaccompanying drawings, in whieh Figure 1 is a sectional perspective viewshowing the invention appliedto a pipe. Fig. 2 is a similar view showinga portion of the external binding-envelope unbuttoned. Fig. Sis atransverse sectional view. Fig. 4 is a perspective view of the externalbinding-envelope, looking at the inside thereof; and Fig. 5 is alongitudinal sectional view of the hind ing-envelope, taken through thebuttons.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherei.1

The numeral 1 indicates an internal layeror sheet of asbestus or othermaterial prepared, preferably, as a fire-proof paper and adapted to restdirectly in contact with a steam-pipe, 2, or other radiating-surface tobe covered and protected. A layer or sheet of paper formed with parallelcorrugations 3 running lengthwise is arranged around the internal layeror sheet with thealt-ernate corrugations resting thereupon, while theother alternate corrugations are cemented or otherwise socured to asheet, 4, of paper, which constitutes a supporting-back for thecorrugated paper sheet.

A course or layer, 5, composed of asbestus and hair felted together, ofconsiderable bulk or thickness, is placed upon the inner corrugatedpaper sheet, and upon this felted course is an outer sheet, (3, of paperformed with parallel corrugations '7, running lengthwise and alternatelybearing upon the felted course, while the other alternate corrugationsare cemented or otherwise secured to a supporting-back, S, composed ofpaper.

The inn er corrugated sheet, 3, and the outer corrugated sheet, (3,constitute within the jacket two sets of parallel separated dead-airchannels or spaces which extend longitudinally, the inner set being atthe inside of the felted course or layer 5 and the outer set at theoutside of the said course or layer, whereby the jacket in its capacityto prevent the radiation of heat is rendered very efficient, desirable,and suitable for the purpose designed.

The backin -sheets 4c and 8 serve to support and preserve the corrugatedshape of the paper sheets and prevent the corrugations from beingcrushed in when binding the jacket upon a steam-pipe or otherradiatingsurface.

The several layers or sheets described are prepared ofsubstantially-equal dimensions to form a jacketsection, and they arethen-bent around the steam-pipe or other object and brought intocylindrical form, in which position the jacket is secured by an externalbinding envelope, 9, of suitably prepared duck, canvas, cotton cloth, orother textile fabric suitable for the conditions required. This canvasor other textile sheetis designed to be detachably secured, and for thispurpose it is provided remote from one longitudinal edge with a row ofbuttons, 10, leaving a projecting extension-flap, 11, to underlie theopposite longitudinal edge, which latter is supplied with a row ofbutton-holes, 12, coinciding with the buttons and adapted to be engagedtherewith. The width of the external envelope is such that when placedaround the non conducting jacket it binds the latter closely and crowdsit upon the pipe or other object in such manner that when the parts arebuttoned together the whole presentsa smooth appearance.

The edge of the envelope having the button-holes is retained in astretched or distended condition by an inserted wire, 13, locateddirectly at and along the outer ends of the button-holes, so that thelatter are braced and prevented from tearing out. The opposite edgeportion where the buttons are placed is retained in a stretched anddistended con dition by awire, 14, which also subserves the function ofsecuring and holding the buttons, this being effected by providing thelatter with shanks having eyes 15, which are passed through theenvelope, so that the stretching or distending wire extends through sucheyes at the inside of the envelope.

The wires 13 and 14 are preferably flexible or bendable to facilitatethe application of the envelope to a non-conducting jacket, but they aresufficiently strong and substantial that while they stretch and distendthe edge portions of the fabric they also distribute the strain on thebuttons and button-holes longitudinally along the envelope, and thuseffectually prevent the latter from tearing out and permit it to besecured in as taut condition as occasion may demand.

By the construction set forth the jacket or covering can be made insections of any desired length, and the external envelope may in itsapplication be made to constitute a practically-co11tinuous casing byextending the end of one section so as to overlap and be buttoned uponthe end of an adjacent section. The wired edges of the envelope renderthe same durable and materially increase its efficiency and enable it tobe applied smoothly and symmetrically. The extension-flap 11 to underliethe button-hole edge is very desirable in connection with the buttoningof the parts together, and the envelope as an article is very useful,since it can be used in connection with various non-conducting jacketsor coverings. The envelope being capable of general application andbeing a separate and independent part from the jacket, adapted to beremoved and replaced at will without disturbing the jacket or coveringto which applied, is more useful and desirable than those structureswherein the body of the jacket itself is supplied atthe edges with hooksto receive a lacing-cord for drawing the edges of the jacket together,so that they abut one against the other.

In practice the non-conductin g jacket is fashioned and fitted to thepipe or other object, and subsequently the external bindingenvelope isapplied around the jacket, drawn closely thereupon, and then buttoned,with the extension-flap of the button edge underlieing the button-holeedge, thus making a close joint Without employing cement, cords, annularbands, or stitching.

I do not confine myself to the backing-sheet of paper on thecorrugation, though this construction will give the most satisfactoryresults. The wires at the edge portions of the envelope should be heldagainst longitudinal displacement or movement, and since econ omy inthis type of articles 'is desired, any undue longitudinal movement isprevented, as here shown, by simply bending the extremities of the wiresinto hooks 16, which engage or interlock with the end edges of theenvelope.-

If desired, the hooks may be further secured by sewing them to theenvelope.

The interiorcorrugated paper sheet by providing the separated channelsto form deadair spaces effectually avoids charring or burning of thehair or other material in the course or layer 5 resting thereupon.

I do not broadly claim dead-air spaces in a non-conducting jacket orcovering, nor do I broadly claim an external binding-envelope; but,

Having thus described my invention, what I claim is 1.
